After years of water drive development, there are great differences in the development status, water flooding degree and pressure maintenance level of each block on the plane and vertically. Relying solely on water drive to improve the development effect has limited potential, so it is urgent to change the development mode. Chemical flooding technology is an important way of tertiary oil recovery. By injecting polymer solution with a certain viscosity into the formation, it can improve the oil washing efficiency and expand the swept volume, so as to improve the effect of thin oil development. In August 2017, polymer flooding pilot test was carried out in 6 well groups of du18 block, Shu3 District, Shuguang Oilfield.展开更多
